Did you know we sell fire protection valves?

Ready for collection today is a 4” Grooved Wet Alarm Valve Set Fully Trimmed c/w Grooved Monitored Butterfly Valve, x2 Couplings, Pressure Switch and Gauges.

The alarm check valve works as a check valve by preventing the reverse flow of water from the system piping to the water supply. The valve is trimmed with a water bypass line, which has an in-line swing check valve. The bypass line allows pressure surges to enter the system and to be trapped above the alarm check valve’s clapper without the clapper lifting and causing false alarms.

When a significant flow of water occurs, such as from an open sprinkler, the alarm valve’s clapper lifts and allows water to enter the system. Simultaneously, water enters an intermediate chamber, which allows the water to activate an alarm either through a water motor alarm or through a water pressure alarm. These alarms continue to sound until the flow of water is stopped.

The alarm check valve is made from high strength, low weight ductile iron, and offers easy access to all internal parts. All internal parts are replaceable without having to remove the valve from the installed position. The rubber clapper seal is easily replaced without removing the clapper from the valve. The valve is painted inside and out to increase corrosion resistance.

The cULus, FM approved version of the valve station valve can be installed in vertical orientations, and it can be used in both constant and variable pressure systems when the optional retard chamber is included in the trim piping. The VdS, CE, LPCB, GOST trim version can only be installed vertically. All versions of the valve are available grooved x grooved only.

The valve is available 1½ – 8″/40 – 200 mm. Standard grooved dimensions conform to ANSI/ AWWA C606.
